IRIX 11mm f/4 Blackstone

Lens Description: Distinguished by its refined physical construction, the 11mm f/4 Blackstone Lens from Irix is an ultra-wide prime designed for Nikon F-mount DSLRs. As a rectilinear lens, the advanced optical layout makes use of aspherical, extra-low dispersion, and high-refractive index elements to control distortion and aberrations for accurate, and sharp rendering with a high degree of clarity and color accuracy. Additionally, a Neutrino coating has also been applied to the lens to control flare and ghosting for improved contrast when working in strong lighting conditions.

Photography Life Review Summary: Anybody buying this lens should know that this is a manual-focus-only lens. In this ultra-wide spectrum, it is not such a problem – Irix offers a well-designed manual focus ring with hyperfocal scale, focus lock and focus snap at infinity. The Irix 11mm f/4 is a lens for rather special purposes and I do not recommend starting with it to anyone who has not photographed with an ultra wide-angle lens yet. Creative and advanced photographers looking for new tools and perspectives may feel attracted to this lens though, so I would certainly recommend them to look into this offering from Irix.
